ADJUSTABLE CRUTCH-TIP.

To 0711071 0m it may concern Be it known that I, WnLnoN A. L. HOFF, acitizen of the'United States, residing at Edmond, in the county ofOklahoma and State of Oklahoma, have invented certain new and usefulImprovements in Adjustable Crutch-Tips, of which the following is aspecification.

This invention relates to an improved crutch and the principal object ofthe invention is to provide an improved type of crutch end, theresilient core thereof being adjustably held in place by improved meanswhereby the core can be gradually fed out of the lower end portion ofthe crutch.

Another object of'the invention is to so construct this crutch that whenthe core is worn out, a new one can be easily put in place.

This invention is illustrated in the accompanying drawings, wherein Fiure 1 is a view showing the improved crutc in elevation. Fig. 2 is anenlarged sectional View through the lower portion of the crutch.

This crutch is provided with the side bars 10 connected by the hand grip11 and having their lower ends secured in the sleeve 12. This sleeve 12may be connected with the side bars 10 in any. suitable manner as thesubject matter of this invention relatesto the manner of adjustablyholding the core 13 within the sleeve. This core 13 which is preferablyformed of rubber, fits within the lower end portion of sleeve 12 and isprovided at its upper end with openings through which the wires 14 pass.These wires 14 are bent to engage the head 15 of the inner sleeve 16through the openings 17 and it will thus be seen that the core will besecurely connected with the sleeve 16. This sleeve 16 is provided with aplurality of openings 18 extending in spiral courses around the sleeve,each of the openings being positioned diametrically opposite a secondopening, so

' that the bolt 19 can be passed through the sleeve 12 and through aselected set of the openings 18. By having the openings 18 extend inspiral courses around the sleeve 16, the sleeve 16 can be adjustedlongitudi- Specification of Letters Patent.

can be easily and quickly adjusted. This will permit the crutch to beregulated. ac-

cording to the length desired. It very often happens that a crutch willbe either just a little too long or a little too short but with thisconstruction, the exact length can be readily obtained.

A crutch including a terminal sleeve, a carryingsleeve slidably mounted in said terminal sleeve and provided with a headatits lower end and. having its walls provided with openings adjacentthe head, a core fitting within said terminal sleeve, wires passedthrough said'core and having their end portions bent upwardly andpassing through the openings in the walls of said carrying sleeve toengage the head thereof and releasably connect the core with thecarrying sleeve, and means for releasably holding said carrying sleevein an adjusted position within said terminal sleeve.
